摘要
钠冷快堆反应堆安全壳边界在安全壳整体密封试验阶段、正常运行期间存在人员进出或应急逃生的需求,因此在人员进出反应堆安全壳大厅边界设置双道连锁人员闸门。与压水堆的人员闸门相比,钠冷快堆人员门承受的绝对压力水平较低,但其需要在钠火事故下保持安全壳边界的完整性。因此设计一套可靠的连锁控制系统对于钠冷快堆的运行安全显得尤为重要。
During the overall containment sealing test phase and normal operation period of the sodium cooled fast reactor containment boundary,there is a need for personnel access or emergency escape,so a dual interlocking personnel gate is provided at the boundary of the reactor containment hall for personnel access.Compared to the personnel gates of pressurized water reactors,the personnel gates of sodium cooled fast reactors bear a lower absolute pressure level,but they need to maintain the integrity of the containment boundary in the event of a sodium fire accident.Therefore,designing a reliable interlocking control system is particularly important for the operational safety of sodium cooled fast reactors.
